Description

Technical Field

[0001] The utility model relates to the field of transfer equipment, in particular to a tire transfer device. Background Art

[0002] Tires need to be transferred between different workstations during processing. Traditional transfer mechanisms for tires often employ a mechanical gripper mounted on a manipulator. While this approach can achieve tire transfer, it is costly. Traditional rotary clamping mechanisms utilize multiple discs, with radial movement of claws connected to the discs to open and close the claws for gripping. However, this mechanism lacks effective sensing components, preventing timely detection of claw movement, reducing work efficiency.

[0003] For example, Chinese patent publication number CN114799975A discloses a disc clamping device comprising: a first disc, a second disc, and a third disc coaxially stacked and independently rotatable; at least one claw mounted on the first disc; and a drive cylinder, which drives the second disc between the first and third discs to rotate, the second disc cooperating with the first disc to convert the rotational motion provided by the drive cylinder into linear motion of the claw toward or away from the center of the disc, wherein each of the at least one claw is equipped with a slider portion and a slide rail portion, the slider portion and the slide rail portion cooperating with each other to enable the claw to move between an open position and a clamped position. The above-mentioned disc clamping device achieves engagement by moving multiple claws radially along the disc. However, when the above-mentioned disc clamping device is raised or lowered, the claw cannot detect the product in time during the descent, thereby affecting work efficiency.

[0004] In view of this, it is necessary to provide a tire transfer device. Summary of the Invention

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 and Figure 2As shown, the tire transfer device provided in the embodiment of the present application includes a fixed base 1, a lifting base 2 vertically slidingly arranged on the fixed base 1, a driving mechanism 3 fixedly arranged on the fixed base 1 for driving the lifting base 2 to move up and down, a rotating base 4 horizontally rotatingly arranged on the lifting base 2, a first cylinder 5 provided on the lifting base 2 for driving the rotating base 4 to rotate horizontally, a first annular plate 6 fixedly provided on the rotating base 4 and having an annular groove on its outer periphery, a second annular plate 7 provided below the first annular plate 6 and coaxial with the first annular plate 6, and a plurality of annular plates 7 arranged coaxially with the annular grooves. The components include a rolling connection 8 that is rollingly connected to the groove and fixedly connected to the upper end of the second annular plate 7; a plurality of claws 9 circumferentially arranged on the first annular plate 6 and sliding in the radial direction; a plurality of arcuate portions 10 circumferentially arranged on the second annular plate 7 and corresponding one-to-one with the claws 9; a push-pull assembly 11 fixed to the rotating base 4 for driving the second annular plate 7 to rotate about its axis; a pressure strip 12 hingedly connected to the claw 9; and a proximity switch fixed to the claw 9 for sensing the position of the pressure strip 12. One end of the claw 9 is located within the center of the second annular plate 7, and the other end is slidably connected to the arcuate portion 10. The lifting mechanism is a hydraulic cylinder.

[0020] In actual use, the push-pull assembly 11 drives the second annular plate 7 to rotate, causing the claws 9 to retract. The drive mechanism 3 then drives the lifting seat 2 to descend, driving the rotating seat 4. When the pressure strip 12 rotates against the tire's sidewall until the claws 9 extend into the tire's inner rim, the proximity switch senses the movement of the pressure strip 12 and sends a signal to the external PLC control system. The PLC control system then sends a control signal to cause the push-pull assembly 11 to rotate the second annular plate 7, causing the arc portion 10 to drive the claws 9 to expand radially, tightening the tire from the inner rim, and completing the tire pickup. The drive mechanism 3 then drives the lifting seat 2 upward, causing the drive mechanism 3 to drive the lifting seat 2 upward, and the first cylinder 5 to drive the rotating seat 4 to rotate horizontally. The drive mechanism 3 then drives the lifting seat 2 downward. After the tire is placed in the predetermined position, the push-pull assembly 11 drives the second annular plate 7 to rotate, causing the arc portion 10 to retract the claws 9.

[0021] In the above design, the tire can be quickly fixed and transferred, effectively reducing costs and improving the efficiency of tire transfer.

[0022] Specifically: Figure 3As shown, the claw toe 9 includes a linear guide 91 that is slidably connected to the lower end surface of the No. 1 disc, a fixed block 92 that is fixedly connected to the lower end of the linear guide 91, a splint 93 arranged at one end of the fixed block 92 and located in the center of the No. 2 annular plate 7, a No. 1 inclined plate 94 that is arranged on the outside of the splint 93 and is inclined upward, a No. 2 inclined plate 95 that is arranged at the lower end of the splint 93 and is below the No. 1 inclined plate 94 and is inclined downward, and a cam follower 96 that is arranged at the other end of the fixed block 92. The No. 1 inclined plate 94, the No. 2 inclined plate 95 and the splint 93 form a slot for clamping. The outer edges of the splint 93, the No. 1 inclined plate 94 and the No. 2 inclined plate 95 are all parallel to the outer periphery of the No. 2 annular plate 7. The cam follower 96 is rollingly connected to the arc portion 10, and the arc portion 10 is an arc groove.

[0023] In actual use, when the second annular plate 7 rotates, the inner wall of the arcuate groove rolls with the cam follower 96, driving the cam to move radially along the second annular plate 7. This causes the cam follower 96 to synchronously move the fixed plate, clamping plate 93, first sloping plate 94, and second sloping plate 95. When positioning and securing the tire, the inner ring of the tire is secured via the clamping groove.

[0024] In the above design, the structural design and specific implementation of the claw 9 can effectively fix the tire.

[0025] Specifically: Figure 1 and Figure 3 As shown, the claw toe 9 also includes a vertical plate 97 fixedly arranged at the upper end of the No. 1 inclined plate 94, a limit strip 98 horizontally fixedly arranged on one side of the vertical plate 97, and a horizontal column 99. The vertical plate 97 is provided with a mounting groove for installing a proximity switch. The pressure strip 12 includes a mounting sleeve 121 rotatably connected to the horizontal column 99, and a rotating rod 122 fixedly connected to the outer side of the mounting sleeve 121. The rotating rod 122 is located between two adjacent claw toes 9. Under the action of gravity, the lower end of the rotating rod 122 protrudes from the lower end of the No. 2 inclined plate 95, and the limit strip 98 is used to abut against the upper end of the rotating rod 122.

[0026] In actual use, when the tire needs to be positioned and fixed, as the driving mechanism 3 drives the lifting base 2 to move downward, the lower end of the pressure strip 12 first contacts the sidewall of the ship and rotates around the horizontal column 99 as the lifting base 2 descends until the claw 9 extends into the inner ring of the tire to complete the positioning and fixing preparation. At this time, the rotating rod 122 rotates to a position sensed by the proximity switch.

[0027] In the above design, the structural design and specific implementation of the claw 9 can effectively ensure the perception of the tire position and ensure the accurate positioning and fixation of the tire.

[0028] Specifically: Figure 1 and Figure 2As shown, the rolling connection member 8 includes a support 81 fixedly arranged on the upper end surface of the second annular plate 7, a ball bearing 82 whose inner ring is fixedly connected to the support 81, and an outer ring of the ball bearing 82 is rollingly connected to the annular groove.

[0029] In actual use, when the second annular plate 7 is driven to rotate by the push-pull assembly 11 , the second annular plate 7 drives the support 81 to rotate synchronously, so that the ball bearing 82 rolls along the annular groove.

[0030] In the above design, the structural design and specific implementation of the rolling connector 8 can effectively realize the rotational guidance of the second annular plate 7.

[0031] Specifically: Figure 1 and Figure 4 As shown, the push-pull assembly 11 includes a No. 2 cylinder 111, a connecting strip 112, a bolt and a seat body 113 rotatably set at the upper end of the No. 2 annular plate 7. The seat body 113 is fixedly set at the upper end of the No. 2 annular plate 7. The seat body 113 is provided with a horizontal through hole for installing the connecting strip 112 and a vertical groove 130 vertically connected to the horizontal through hole. The cylinder body of the No. 2 cylinder 111 is hingedly set on the rotating seat 4. The output end of the No. 2 cylinder 111 is fixedly connected to the connecting strip 112. The connecting strip 112 is provided with a plurality of screw holes 120 arranged along the length direction. The bolts pass through the vertical groove 130 and are threadedly connected to the screw holes 120.

[0032] In actual use, the connecting bar 112 is driven horizontally by the second cylinder 111, so that the connecting bar 112 drives the second annular plate 7 to rotate through the base 113. When the connection position of the connecting bar 112 and the base 113 needs to be changed, the bolts are removed, the connecting bar 112 is loosened along the horizontal through-hole, the original screw hole 120 corresponding to the vertical slot 130 is changed, and then the bolts are passed through the vertical slot 130 and threadedly connected to the screw hole 120.

[0033] In the above design, the structural design and specific implementation of the push-pull assembly 11 can effectively and quickly change the driving stroke of the second annular plate 7, so that the spacing of the claw toes 9 that is contracted or opened can be easily adjusted to adapt to different types of tires.

[0034] To further explain in detail, it should be understood that the above is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
